I'll be visiting Boulder on Nov. 7-9. Can anyone recommend a quality provider? Is Denver too far away?

Lots of gals in Denver. Fewer specialize in Boulder. Look for gals in North Denver.  DTC where many are is a real hike from Boulder.  I was in Denver for many years before moving to FL.  TER not so active in Denver as is TOB (for reviews) and Escort Boards (for ads).

Try Melinda Madison.  I'm not sure if she will be in town, but she would be my bet and has many reviews on here plus a flawless rep.

Pm me if you are interseted fo details.
